The Interlock-18 Fibered IDC Occlusion system is a detachable coil that is designed to rapidly occlude blood flow in the vessels of the peripheral vasculature. The system is designed around the following features:

Interlocking Arms:

  • A small interlocking arm on the end of the coil’s pusher wire is mated to another small arm on the end of the coil itself.
  • Once interlocked, these two arms cannot separate while inside a microcatheter with an appropriate (0.021”) inner lumen diameter.
  • When the interlocked arms are pushed outside of the microcatheter lumen and into free space, the arms are designed to simply separate from one another, thus detaching the coil.

Dense Network of DacronTM Fibers:

  • Every coil contains multiple dense network of DacronTMFibers, each designed to catch blood cells and propagate the formation of thrombus.
  • A close-up image of Dacron Fibers shows that the structure of the fiber strands are structured, yet porous, allowing for rapid thrombosis.

Coil Shapes:

The 2D Helical shape is designed to provide optimal anchorability, as the helical shape allows the coil to be in constant, consistent contact with the wall of a straight or tapered vessels.   The 2D Helical shape is available in diameters of 2mm – 22mm and lengths of 4cm – 60cm.

Common applications for a 2D Helical shaped coil include, but are not limited to the following:

  • Gonadal vein embolization
  • Visceral artery aneurysms
  • Hepatic arterial embolizations

The Diamond shape is designed to maximize occlusive power by tapering the distal and proximal ends of the coil, maximizing cross-sectional flow disruption.

Common applications for a Diamond shaped coil include, but are not limited to the following:

  • Gastrointestinal bleeding
  • Visceral artery aneurysms
